3-DIMENSIONAL SOUND SYNTHESIS BASED ON HEAD-RELATED TRANSFER-FUNCTIONS

A common technique for synthesizing three-dimensional sound makes use of head-related transfer functions (HRTFs). The HRTFs made available t o the public by Gardner and Martin of MIT Media Lab. are used with the intent to refine them so as to exaggerate the perceptual differences for sounds coming from different directions, and to emphasize the pinn a effects. With the refined HRTFs reduced front-back reversal rates an d improved ability to locate moving sources are demonstrated.
